I Application filed April 18, 1921. Serial No. 462,367.

To all whom it may concern:

Be it known that I, BENEDICT D. JAoovn'r'r,

a citizen of the United States, residin at Lorain, in the county of Lorain and state of Ohio, have invented certain new and useful Improvements in a' SewersRefilling Tray; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is to provide a refilling tray for use in connection with excavating operations as for example in laying a sewer or the likewherein the earth is excavated and after the sewer pipe has been laid it is necesary to replace so much of the earth as the trench will receive properly settled and packed, and the particular object is to facilitate the replacing of the earth after the sewer or main has been positioned,

. to avoid the tedious operation of shoveling;

and with this object in View the invention consists in a construction and comb nation of vparts'of whlch a preferred embodiment is shown in the drawing, wherein: Figure 1 1s a plan vlew of an apparatusembodying the invention.

Fig. 2 is a longitudinal sectional view of the same. I

Fig. 3 is a detail view of one end of one of the dumping plates and the connected links for securing the same in series.

The device consists essentially of a series of dump plates 10 having terminal trunnions 11 connected in series by links 12 to form a tray of any desired extent or area,-the links having openings 13 through which the trunnionsextend and being held in place by cotter pins 14 or the equivalent thereof.

The trunnions or axes of the dump plates are arranged at one side edge of each plate thereby leaving the other edge free for swinging movement, and the 'dumpplates are spaced by the links so that the free edge of one plate underlaps the pivotal or axial edge of the next plate to prevent material thrown upon the tray during the excavating operation from. passing therethrough. V

After the sewer pipe ormain hasbeen laid and'itis desired to replace the earth in the trench or excavation a draft link 15 is connected with the draft eyes 16 at one end of the tray and either horses or a. tractor may be connected with the links for movmg the tray toward and over the trench so that as the same extends over the opening the plates will swing downward and deposit the earth in the cavity.

The draft link'may as illustrated be provided with terminal hooks 17 for engagement with the draft eyes 16 andbefore the commencement of the excavation a number of these trays may bearranged at the side of the line on which the sewer or main is to be laid and obviously, as eachtray is unloaded in the progressive refilling of the trench it may be carried forward along the line of the work and positioned to receive a new load.

Having thus described the invention, what I claim is 1.. A refilling tray having a plurality of plates maintained in load-retaining relation by. contact with the ground, and means mounting the plates for relative movement to discharge the load through disengagement of the plates with the ground and weight of the load thereon as the tray spans op posed walls of a trench.

2. A refilling tray having a plurality of" plates maintained in load-retaining relation by contact with the ground, and means mounting the plates for relative movement to discharge'the load through disengage ment of the plates with the ground and weight of the load thereon as the tray spans opposed walls of a trench, consisting of trunnions on the said trunnions. v

3. A refilling tray having a plurality of plates, and links pivoted on plates maintained in load-retaining relation by contact with the ground, and means In testimony whereof I aflix my signature i;-

in presence of two witnesses.
